Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100228, here are decompositions:

  • 59 + 100169 = 100228
  • 179 + 100049 = 100228
  • 239 + 99989 = 100228
  • 257 + 99971 = 100228
  • 347 + 99881 = 100228
  • 389 + 99839 = 100228
  • 419 + 99809 = 100228
  • 461 + 99767 = 100228

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,228 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 100228 first appears in π at position 839,728 of the decimal expansion (the 839,728ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
